TABULATOR STOP CONTROL ARRANGEMENT Filed Nov. 1I 1961 ww v United States Patent M 12 Claims. (ill. 197-179) The present invention relates to a tabulator stop control arrangement, and more particularly to a tabulator stop setting and clearing arrangement for a power operated business machine, such as an electric typewriter.

The tabulator stops of manually operated typewriters, as well as of electric typewriters according to the prior art, are set and cleared by manual operation of corresponding keys so that the force required for setting and clearing the stops is supplied by the operator.

The conventional constructions have the disadvantage that a considerable force is required from the operator, as compared with the force required for actuating the other keys of the electric typewriter. Furthermore, the operation is carried out through a complicated linkage which results in a slow operation. It is one object of the invention to overcome the disadvantages of the known tabulator stop control arrangements and to provide a tabulator stop control arrangement of simple construction, which rapidly operates, and requires very little force for the actuation of the control keys.

Another object of the present invention is to provide a tabulator stop control arrangement in which the operator only initiates the operation, while the force required for the operation is supplied by a drive means.

Another object of the present invention is to provide a tabulator stop setting and clearing arrangement for an electric typewriter in which the force for setting and clearing the tabulator stops is supplied by the electric drive means of the typewriter, for example by the rotating power roll.

Another object of the present invention is to provide a single actuating means cooperating with the power roll of an electric typewriter for selectively setting or clearing tabulator stops under control of a setting key or clearing key, respectively.

With these objects in view, a tabulator stop control arrangement according to one embodiment of the invention comprises tabulator stop means which may be arranged on the paper carriage of the typewriter and are shiftable between a cleared inoperative position and a set tabulating position; drive means, such as a power roll; control means for shifting the tabulator stop means and being movable to and from an operative position connected to the power roll so that the control means are actuated by the power roll to shift the tabulator stop means; and operating means, such as a setting key and a clearing key, connected to the control means for efiecting movement of the same to and from the operative position. Since the power roll operates the control means in the operative position thereof, the tabulator stop means is shifted by the control means upon operation of one of the keys.

The preferred embodiment of the invention comprises a set of tabulator stops arranged in a row on the paper carriage of the machine; first shifting means for setting the tabulator stops, and second shifting means for clear ing the tabulator stops; a power roll; actuating means including a movable member supporting a turnable eccentric part and movable to and from an operative position in which the eccentric part is engaged and turned by the power roll so that the actuating member is shifted to an actuated poscition; first and second coupling means for respectively connecting said actuating means with said 3,150,755 Patented Sept. 29, 1964 first and second shifting means; a setting key connected to the first coupling means, and a clearing key connected to the second coupling means so that upon actuation of one of said keys, said actuating means are coupled to the respective shifting means; and linkage means connecting the keys with the actuating means. The linkage means and coupling means are arranged in such a manner that the turnable eccentric part is moved to the operative position thereof by any one key after one of the shifting means is coupled with the actuating means. Consequently, the power roll moves the actuating means so that the same effect through the respective coupling means the operation of the respective shifting means so that the tabulator stop is shifted which is aligned with the respective shifting means in the momentary carriage position.

The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specifig embodiments when read in connection with the accompanying drawings, in which:

FIG. 1 is a fragmentary side view, partially in section, illustrating a tabulator stop setting and clearing arrange\ ment according to one embodiment of the invention;

FIG. 2 is a fragmentary section taken on line 2,2 on the left of FIG. 3b.

FIG. 3a and FIG. 3b are rear views of the apparatus viewed in the direction of the arrow 3 in FIG. 1 with parts of the mechanism omitted for the sake of simplicity and clarity.

Referring now to the drawings, a tabulator stop setting key 1 and a tabulator stop clearing key 10 are arranged in the region of the keyboard of the typewriter transversely spaced from each other in a conventional manner, so that the tabulator key can be arranged between set key 1 and clear key 1a. Each key 1 and 1a has a key lever 2 which is articulated to a linkage lever 5 having a part projecting toward the operator and being mounted for turning movement on a pivot pin 5b which is secured to a frame part 3. A member 12 is also secured to frame part 3 and has projections 12a for springs 4 which are connected to linkage levers 5 and hold linkage levers 5 and keys 1 and 1a in the illustrated normal position in which projection 5a abuts a stop 30 on the frame of the machine. Member 12 has an upper portion formed with slots in which key levers 2 are guided.

The linkage levers 5 have projections 50 to which coupling members 6 and 6a are, respectively, articulated. Each coupling member has a long portion extending from the front of the machine to a region below the paper carriage, and an upright portion 6', 6a from which a coupling part 7 projects. When key 1 or key 1a is depressed, the respective linkage lever 5 will turn in counterclockwise direction and the respective coupling member 6 or 6a will be shifted to the right as viewed in FIG. 1 together with coupling part 7.

A guide lever 9 is mounted on frame part 3 and is articulated to the arm 8b of a linkage member 8 which has another arm 8a, and a third arm 80. Ann is articulated to a lever 10 mounted on the pivot means 5b on frame part 3. A corresponding lever 10', not shown, is also mounted on pivot means 5b on the other side of the linkage levers 5, and levers 10 and 10' are connected by a rod 11 extending across the projections 5a of linkage levers 5. When one of the keys 1 or 1a is depressed the respective linkage lever 5 will turn in counter-clockwise direction, displace rod 11, and turn lever 10 in counter-clockwise direction so that linkage 3 member 8 will be pulled down. Linkage member 8 is also guided in a slot of member 12.

The machine has conventional lateral frame parts, not shown, between which a shaft 13 extends. Actuating means are mounted on shaft 13 and include an actuating member 16 mounted for angular turning movement on shaft 13, and having two projections 16a and 16b on which arms 17 and 18 are pivotally mounted. Arms 17 and 18 are biased by springs 17a and 18a to turn toward each other. Actuating member 16 turnably supports an eccentric part which has four peripheral edge portions'. A stop 15a is secured to the eccentric part 15, and projects into the region of the spring-loaded arms 17 and 18. Actuating member 16 has a downwardly extending arm which is connected by a link 22 to a doublearmed lever 24, 26 supported on a pivot means 25 on a bracket 23 on the machine frame. Arm 26 is connected by a link 27 to a lever 29 which is secured toa shaft 28 so that shaft 28 is angularly displaced. A pair of stops 30 and 30a limit movement of arm 29.

A substantially U-shaped member includes a pair of arms 31a and 31b which are fixed to shaft 28, and a yoke portion 31 provided with a transverse coupling portion 32 which cooperates with the coupling parts 7 of coupling members 6 and 6a. Members 6, 6a 7, 32 constitute coupling means. When a coupling member 6 or 6a is shifted to the right by operation of the respective key 1 or 1a, coupling part 7 will be located above coupling portion 32 so that turning of member 31, 31a, 31b by shaft 28 under control of actuating member 16 will raise the respective portion 6' while the respective coupling member turns on the pivot pin of projection 50 of linkage lever 5. A spring 20 is connected to the frame and to actuating member 16 and urges the same to turn in counter-clockwise direction until the lower end of actuating member 16 abuts stop 21 on the frame of the machine in the position illustrated in FIG. 1.

A stop lever 14 is also mounted on shaft 13 and has an arm 14a carrying a pin 14b slidably mounted in a slot in arm 8a of linkage member 8. Stop lever 14 has at the lower end thereof two transverse projections 14c and 14d which are located in the region of the stop 15a on the eccentric part 15. In the illustrated normal position of the actuating means, arm 17 abuts stop 15a and urges the turnable eccentric part 15 to turn in clockwise direction so that stop 15a abuts the transversal projection 14c of stop lever 14. In this position, the peripheral surface of eccentric part 15 is spaced from the power roll 19 which is mounted in a conventional manner in the frame of the machine and normally rotates in direction of the arrow for actuating the type lever actions.

A tabulator stop support bar 44 is mounted on the paper carriage of the machine and supports a set of tabulator stops 45. Each tabulator stop is shiftable between the cleared inoperative position shown for stop 45 in FIG. 2, and the set tabulating position. A tabulator stop 45 in the set tabulating position projects downwardly into the region of stop means not shown, provided in a conventional manner on the stationary tabulator frame 35, so that the carriage is stopped when set tabulator stop 45 abuts the stationary stop means during the carriage movement. Frame is supported on a pair of rods 33 and 34.

First shifting means are provided for setting the tabulator stops 45, and second shifting means are provided for clearing the tabulator stops 45. The first shifting means include a push bar 36 having a transverse projection 36a located directly above the portion 6' of coupling member 6 and guided in a slot of tabulator frame 35. The upper end of push bar 36 is articulated to a lever 38 which is mounted on frame 35, and has a free end portion articulated to a shifting member which is also guided in a slot in the upper part of frame 35 and has a transverse projection 40a. A connecting member 46 has a threaded part and is adjustably connected to por- 4, tion 40a. The end of member 46 is articulated to a double armed lever 47 which is pivotally mounted on a stationary frame part and has a portion 47a, best seen in FIG. 1, which projects into the region of the row of tabulator stops 45 and is located above the same. A spring 4711 biases lever 47, and a spring 42 connects push bar 36 with frame 35 so that the first shifting means normally assume the position illustrated in the drawing.

The second shifting means includes a push bar 37 guided in a slot of tabulator frame 35 and having a transverse projection 37a located directly above the portion 6a of coupling member 6a. The upper end of push bar 37 is articulated to a lever 39 which is mounted on frame 35 and has a free end articulated to a shifting member 41 guided in a slot in the upper part of frame 35 and having an upper end located in the region of the row of tabulator stops 45, as best seen in FIG. 2.

A spring 43 urges the second shifting means into the illustrated normal position in which a projection on push bar 37 abuts frame 35.

The tabulator control arrangement is operated as follows:

When a tabulator stop 45 i to be set, the carriage is moved to the desired tabulating position, so that lever 47 is located above the respective tabulator stop 45 as shown in FIG. 3a. The set key 1 is depressed by the operator so that linkage lever 5 turns in counter clockwise direction and shifts coupling member 6 to a position in which coupling part 7 is located above coupling portion 32 while the upper edge of portion 6 is still located underneath projection 36a. This position is a first coupling position of coupling means 6, 6a, 7, 32.

The pivotal movement of lever 5 raises rod 11 so that levers 10, 10' turn in counter-clockwise direction so that linkage member 8 and arm 8a are lowered so that stop lever 14 is turned through pin 14]) and arm 14a in clockwise direction so that projection 14c is no longer located in the path of stop 15a. Spring-loaded arm 17 now turns eccentric part 15 a small angle until the periphery of eccentric part 15 engages the rotating power roll 19 so that part 15 is turned. Due to the eccentric shape of part 15, actuating member 16 is turned in clockwise direction against the action of spring 20 so that the linkage 22, 24, 27, and 29 is displaced, and the actuating lever 31a, 3112 with coupling portion 32 is turned in clockwise direction.

Coupling portion 32 raises coupling part 7 with coupling member 6 turning about the pivot on linkage lever 5. The raised coupling member 6 engages push bar 36, and shifts shifting member 40 so that lever 47 is turned and projection 47a pushes downwardly against the respective tabulator stop 45 and shifts the same from the inoperative cleared position shown in FIG. 1 in downward direction to a set tabulating position located in the region of a stationary stop means, not shown, on frame 35. The shifting arrangement described above is now in a first shifting position.

This setting operation is accomplished by turning movement of the eccentric part 15 through an angle of 180. Since projection 14d of stop lever 14 is located in the circular path of movement of stop 15a as long as key 1 is depressed and stop lever 14 is displaced, stop 15a, biased by the spring-loaded arm 18, will abut projection when the periphery of eccentric part 15 scparates from the power roll due to the shape of the peripheral surface of part 15. However, when key 1 is released, a spring, not shown, will effect turning of stop lever 14 to the illustrated normal position so that projection 14d is retracted from stop 15a. Eccentric part 15 is again free to be turned by arm 18 toward the power roll 19, and then by the same to its initial position illustrated in FIG. 1. During such turning movement, coupling portion 32 will be raised again, but since key 1 is in its inoperative normal position, the coupling part 7 of coupling member 6 is no longer located in the path of movement of coupling portion 32, and consequently the shifting means are not actuated during the second part of the turning movement of eccentric part 15.

When a tabulator stop is to 'be cleared, the carriage is moved to a position in which the respective tabulator stop is engaged by the stationary stop means, not shown, in which position shifting member 41 is aligned with the respective tabulator stop 45, as shown in FIG. 3b; The clear key is depressed so that coupling member 6a is shifted and coupling means 6, 6a, 7, 32 is in a second coupling position in which its coupling part 7 is located in the path of movement of coupling portion 32. Upon shifting of the actuating means by the power roll 19, coupling member 6a is raised, and shifts push bar 37 and shifting member 41 so that the same shifts respective tabulator stop 45 to its closed inoperative position. The shifting arrangement is now in a second shifting position.

It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of tabulator stop control arrangements difiering from the types described above.

While the invention has been illustrated and described as embodied in a tabulator stop setting and clearing arrangement operated by the power roll of an electric typewriter, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.

I Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can by applying current knowledge readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence of the following claims.
